Gawayn is a Zany Cartoon in which Princess Gwendolyn is about to be crowned queen before the villainous Duke decides to interrupt, placing a curse upon her which shrinks her down to size... Literally! In order to reverse this curse and regain her lost kingdom (now in the hands of the Duke), she must go on a quest to find the crystal of Gawayn. Accompanying her along the way is knight Sir Roderick, William the young knight-in-training, his sister and sorceress Inept Mage Elspeth, and Xiao Long, skilful in the area of martial arts. Together they set off, experiencing all kinds of adventures, obstacles and setbacks on their journey, meanwhile the Duke and his snarky companion Rex frantically try to stop them using one outrageous scheme after another.
Amplified Animal Aptitude: Griselda the horse seems able to understand what the characters around her are saying most of the time, even seen at some points doing very unhorse-like things, such as reading a newspaper.
Amusing Injuries: Happens all the time, with Sir Roderick being the main victim, but with the Duke also giving him a good run for his money.
Extendable Arms: Practically all the characters have been shown to possess this at times. Notable with Rex, due to being so small, wouldn't be able to open doors or perform many of the other basic tasks he can be seen doing unless this trope is employed.
Fantastic Voyage Plot: In one episode, Gwendolyn and Roderick have to travel inside a dragon to kill the germ causing its acid reflux.
Fast Tunnelling: Xiao Long manages to dig a very long tunnel in an attempt to help himself and the other questers (sans Roderick) escape jail in an episode with a fork.
Fattening The Victim: In one episode, a group of natives feed Sir Roderick plan to sacrifice Sir Roderick to the volcano god. However, they first feed him 27 pizzas to fatten him up and make him a suitable sacrifice.
Furry Confusion: There are a lot of animals present, but they cover an entire spectrum in regards to where they stand anthropomorphically speaking. You have Funny Animal characters like Rex, and then characters which simply show Amplified Animal Aptitude, such as Griselda, and then all kinds in-between.
Laugh with Me: In the first episode, the Duke pauses his his Evil Laugh and asks Rex in annoyance, "Why aren't you laughing?"
Leitmotif: The same ominous piece of music plays every time we get a shot of the Duke's castle, or when the scene simply changes to show what he's up to. The show also has several common tunes which serve as the background music at various points.
Princesses Rule: Gwendolyn is portrayed as the rightful ruler of her kingdom. Her parents have never been seen or even mentioned, however this trope is probably justified in that Gwendolyn was shown as just about to be crowned queen before her kingdom was hijacked.
Road Sign Reversal: The Duke employs this in an episode in order to send the questers off into the wrong direction.
Rex: That is the lamest plan ever! You're gonna get them lost?! How exciting...
Tongue on the Flagpole: Having won a fake Crystal of Gawayn in a game show, Roderick tries to get it to work by licking it. At this point, he discovers it is actually made of ice as it sticks to his tongue.
Trap Door: All of the questers (except Xiao Long) fall victim to this in an episode.
